OptionalappsOptionalcacheExplicit Cache-Control header value to set on the response stored in cache. This gives full control over cache directives (e.g. 'public, max-age=3600, s-maxage=86400').
Cannot be used together with cacheTtl or the cache request option (no-store/no-cache),
as these are mutually exclusive cache control mechanisms. Setting both will throw a TypeError.
Can be used together with cacheTtlByStatus.
OptionalcacheWhether to enable Cache Deception Armor, which protects against web cache deception attacks by verifying the Content-Type matches the URL extension.
OptionalcacheOptionalcacheA request's cache key is what determines if two requests are "the same" for caching purposes. If a request has the same cache key as some previous request, then we can serve the same cached response for both. (e.g. 'some-key')
Only available for Enterprise customers.
OptionalcacheWhether the response should be eligible for Cache Reserve storage.
OptionalcacheMinimum file size in bytes for a response to be eligible for Cache Reserve storage.
OptionalcacheThis allows you to append additional Cache-Tag response headers to the origin response without modifications to the origin server. This will allow for greater control over the Purge by Cache Tag feature utilizing changes only in the Workers process.
Only available for Enterprise customers.
OptionalcacheForce response to be cached for a given number of seconds. (e.g. 300)
OptionalcacheForce response to be cached for a given number of seconds based on the Origin status code. (e.g. { '200-299': 86400, '404': 1, '500-599': 0 })
OptionalimageOptionalminifyOptionalmirageOptionalpolishOptionalr2OptionalresolveRedirects the request to an alternate origin server. You can use this, for example, to implement load balancing across several origins. (e.g.us-east.example.com)
Note - For security reasons, the hostname set in resolveOverride must be proxied on the same Cloudflare zone of the incoming request. Otherwise, the setting is ignored. CNAME hosts are allowed, so to resolve to a host under a different domain or a DNS only domain first declare a CNAME record within your own zone’s DNS mapping to the external hostname, set proxy on Cloudflare, then set resolveOverride to point to that CNAME record.
OptionalrespectWhether to respect strong ETags (as opposed to weak ETags) from the origin.
OptionalscrapeOptionalstripWhether to strip ETag headers from the origin response before caching.
OptionalstripWhether to strip Last-Modified headers from the origin response before caching.
In addition to the properties you can set in the RequestInit dict that you pass as an argument to the Request constructor, you can set certain properties of a
cfobject to control how Cloudflare features are applied to that new Request.Note: Currently, these properties cannot be tested in the playground.
